Japan Electrical Appliance Safety Law is a law enacted to protect consumers from fire and electric shock caused by electrical products. It is a safety standard that applies to almost all household electrical appliances connected to a 100V outlet in Japan. According to the Japan Electrical Appliance Safety Law, manufacturers and importers are obliged to put the PSE mark on suitable products and sell them so that consumers can distinguish them.

PSE mark stands for Product Safety Electrical Appliance & Materials, and it is a mark that indicates that electrical products meet safety requirements.

112 designated electrical appliances (electric products that are predicted to have high risk and are strictly evaluated) that require high safety standards. The PSE mark is in the shape of a diamond.
Category A mark: A factory audit is required for this product category.
